In the world of finance and accounting, credibility isn’t just about your technical expertise or resume — it’s also conveyed through how you speak. The way you use your voice in high-stakes moments (like job interviews, client meetings, or board presentations) can either reinforce your authority or subtly undermine it. Research shows that within the first 10 seconds of speaking, listeners form instant impressions of your competence, authority, and leadership potential based solely on vocal cues . In fact, one analysis of executive speeches found the sound of a speaker’s voice matters twice as much as the content of the message when it comes to audience perception . This means even a highly qualified CFO or Big 4 accountant could inadvertently dilute their perceived authority if their vocal delivery sends the wrong signal.

Unfortunately, we often see talented candidates harm their executive presence with a few common vocal habits. Two of the most talked-about offenders are vocal fry (the low, creaky voice register) and uptalk (raising your tone at the end of a statement, as if asking a question). Other behaviors like excessive filler words (“um,” “uh,” “like”) or a monotone/mumbling delivery can likewise chip away at the impression of confidence and clarity. Let’s examine each of these habits, why they matter for finance and accounting professionals, and how to address them in a constructive way.

Vocal Fry – The Creaky Voice That Falls Flat

Vocal fry refers to a low-pitched, creaky vibration in speech – the kind of crackling tone you hear when someone drops their voice to its lowest register. It’s become common enough (especially among younger professionals) that you might not even notice you’re doing it. However, interviewers and clients often do notice, even if subconsciously. Studies have found that speaking with vocal fry can trigger strongly negative perceptions. In one well-known experiment, listeners judged young female voices with vocal fry as “less competent, less educated, less trustworthy, less attractive, and less hirable” compared to a normal voice . The effect was especially pronounced coming from women’s voices (though men aren’t off the hook either).

Why is this creaky-voice habit such a turn-off in professional settings? Part of it is cultural – fair or not, a “fried” voice is often associated with being young or unserious (think parody of a bored teenager). In an interview or CFO presentation, that’s the last impression you want to give. A vocal fry can also make you sound disengaged or low-energy when you should sound enthusiastic and confident. Imagine ending every answer with a gravelly whimper; you risk losing the “punch” at the end of your sentences, so your statements land weakly. As one communications expert put it, finish your sentence with a whimper instead of a bang and you risk losing credibility .

What can you do about it? First, recognize when you’re using vocal fry – it often happens at the ends of sentences or when you’re speaking with insufficient breath support. To counter it, practice speaking through the end of your sentences with a clear tone. Support your voice with proper breathing (from the diaphragm) so you’re not squeezing out words at a pitch too low for you. You don’t need to artificially raise your voice into an unnatural high pitch; just aim for a strong, steady tone instead of a creak. It can help to record yourself in a mock interview and listen for that telltale crackle. With awareness and practice, you can eliminate most vocal fry from your speech. The payoff? A voice that sounds more confident and mature – ideal for conveying authority when discussing audits, budgets, or strategic plans.

Uptalk – Turning Statements into Questions

Have you ever heard someone state their qualifications as if they were asking about them? For example: “I led a team of five analysts?” – with an upward inflection that makes a solid statement sound unsure. This speech habit is known as uptalk (or “upspeak”), where your intonation rises at the end of a declarative sentence. Uptalk can be a career killer for your credibility. It sends the message that you’re not confident in your own words – as if you’re constantly seeking validation or asking for approval. In an interview setting, uptalk can make even a well-prepared candidate seem uncertain about their own experience (“I managed a $2M portfolio?”) and cause an interviewer to doubt the candidate’s conviction.

Originally a stereotype of “Valley Girl” speech, uptalk is now heard across genders and professions – but that doesn’t make it professionally acceptable. Many business leaders and listeners find it downright grating. In a survey of 700 managers in Britain, more than 70% said uptalk is “annoying”, and 85% described it as a “clear indicator” of insecurity . If you’re presenting financial results to a client or delivering a project update to executives, the last thing you want is your tone of voice hinting at insecurity. Remember that listeners can’t un-hear that question-mark intonation – it plants doubt about your surety on the subject. As communications coach Michelle Zucatti noted, when used chronically, uptalk is perceived as unprofessional and exposing one’s insecurities .

How to fix uptalk: The key is to train yourself to conclude statements with a falling intonation (downward tone) instead of a rise. One trick is to emphasize the second-to-last word in your sentence, then let your tone drop on the final word . For example, practice saying “I led a team of five analysts.” (stress “led” and finish firmly) versus the question-like “I led a team of five analysts?” Additionally, build your awareness: record yourself or ask a colleague to point out if your sentences sound like questions. Oftentimes, uptalk slips in when we’re nervous or unsure about what we’re saying, so thorough preparation can help (if you know your material, you’ll feel less need to subconsciously ask “Is that okay?” with your tone). By speaking in definitive statements, you project confidence. This is crucial in finance roles – whether you’re an auditor explaining compliance issues or a finance VP pitching a budget, your words need to sound certain. The content of your message and your tone should both say: “I know what I’m talking about.”

Filler Words – “Um, You Know, Like…”

Nearly everyone uses filler words occasionally – those little “ums,” “uhs,” “likes,” and “you knows” that slip out when we’re thinking. In moderation, they’re usually harmless. But excessive filler words can become a real credibility killer in interviews and meetings. If every sentence is peppered with “um” or “like,” listeners start to focus on those tics instead of your message. More importantly, a surplus of fillers can make you sound unprepared, indecisive, or lacking confidence in what you’re saying. Think about the impression this gives: a CFO candidate answering, “Um, we had like… around 20% growth last quarter, I think.” The hesitancy and lack of crispness might make the hiring committee wonder if the candidate really knows their numbers.

Scientific research backs up the idea that too many fillers hurt your perceived authority. A recent analysis of public speaking noted that excessive use of fillers can reduce the credibility of the speaker and even impair the audience’s comprehension of the message . Essentially, every “uh” and “you know” is stealing focus from the content and causing your audience to mentally stumble. Often, filler words creep in due to nervousness or speaking too quickly – your brain is catching up to your mouth, and you’re filling the gap with sound. They can also be a habit from everyday speech that becomes painfully obvious in a high-stakes setting like an interview.

How to tighten up your speech: Start by becoming aware of your filler word usage. You might even ask a friend or mentor to mock-interview you and point out every time you say “um” or “like.” Once you’re aware, work on embracing the power of the pause. It’s perfectly okay (even persuasive) to pause silently for a moment to gather your thoughts. Replacing an “um” with a short pause not only makes you sound more confident and thoughtful, it also gives your listener a moment to absorb what you’ve said. Additionally, slow down your speaking pace a touch. Rushing often leads to more filler words, so a measured pace will help you feel in control of your words. With practice, you can speak in complete sentences without crutches. The result: you’ll come across as clear, collected, and credible – just the impression you want to make when discussing complex financial analyses or tax strategies.

Monotone and Mumbling – When Delivery Falls Flat

Finally, let’s address two vocal delivery problems that sit at opposite ends of the spectrum: speaking in a monotone and mumbling. Both can undermine your authority by making your speech less engaging or even difficult to understand.

Monotone means delivering every word on the same flat pitch, with little to no variation or emotion. A monotone voice can make even exciting topics sound dull. Picture an accountant enthusiastically saying (in a droning, flat tone), “I’m really passionate about forensic accounting.” The words and tone just don’t match! Listeners confronted with a monotone delivery tend to zone out or perceive the speaker as disengaged. In other words, monotone speakers are not engaging and have little impact on their audience . If you speak in a monotone during an interview, the interviewer might question your energy, enthusiasm, or even your interest in the role. In client-facing situations, a monotone can be misread as boredom or lack of conviction about your own message – not a great vibe when you’re trying to instill confidence in a financial plan or audit report.

Mumbling is a different problem: it’s when you speak too quietly or indistinctly, so that parts of your words get lost or garbled. This often happens when people talk too fast, fail to open their mouths enough, or drop their volume at the end of sentences. The result is the listener straining to catch your words. Not only is this frustrating for an interviewer or client, it also makes you seem less confident – almost as if you don’t believe you deserve to be heard. In fact, speaking unclearly or under your breath can come across as apologizing for speaking or even being ashamed of your words . One speech coach notes that mumbling is a common issue that “can make you appear less confident and authoritative” at work . Consider how damaging that is in a leadership context: if a controller or finance manager mumbles through a presentation, the team might subconsciously doubt their leadership presence or assume the speaker isn’t sure about what they’re saying.

How to add clarity and life to your voice: If you suspect you’re a bit monotone, focus on adding vocal variety. This doesn’t mean you need to become overly dramatic; just make a conscious effort to vary your pitch and emphasis. Try emphasizing key words in your sentences and ensure you have some inflection (a rise or fall) rather than a constant flat line. A helpful exercise is reading a passage out loud and exaggerating the expressiveness – then dialing it back to a natural, conversational level. For those who speak in a monotone due to nerves, remember to breathe and let your voice be animated by the meaning of what you’re saying. Bringing genuine interest to your topic naturally boosts your vocal energy.

If mumbling is the issue, the first fix is projection: speak up and support your voice with breath so the last words of your sentences don’t trail off. Practice enunciating your words clearly – you can even do tongue-twister exercises or read aloud with a focus on crisp consonants. It might feel silly, but try the classic trick of practicing with a pen between your teeth (it forces you to open your mouth and articulate). Also, slow down a notch. Mumbling often happens when rushing; a deliberate pace gives you time to fully pronounce words. Finally, remember to engage your mindset: you do want to be heard! Remind yourself before an important conversation that your ideas are worth hearing, and adopt a confident posture (sitting or standing tall) when you speak. This mental reset can prevent the timid, shrinking delivery that leads to mumbling. The goal is to sound clear and confident – traits every employer or client expects from a finance professional handling complex information.
